Context
Multi-material 3D printing is my rapid-prototyping playground: going from idea to a working object in a few hours. I model in Autodesk Inventor, pick the material to match the constraints (PLA for the prototype, PETG for mechanical strength, TPU for flexibility), then print in FDM. Over time I've made a wide range of objects, for my own projects and on request from individuals (for instance small replacement automotive parts). I don't run it as a business: it's first and foremost a space for learning and hands-on experimentation, halfway between mechanical design and manufacturing.
Approach / Solution
A few representative builds: • Portable battery winch, my most accomplished piece. A rechargeable winch that lifts about 40 kg in its printed version: I repurposed a small gearmotor fitted with worm screws at both ends to multiply the torque. The same architecture, made in steel, could lift or tow more than a tonne. • 3D-printed robotic arm, assembly of a geared articulated arm (from a provided free model) to explore printed mechanisms, clearances and tolerances. • Illumine (ongoing), a lamp design-and-print project: lampshades printed in spiral (vase mode) for a translucent, textured finish. • Custom automotive parts and repairs, modelled and printed in the material best suited to the use.
Results
A full chain mastered, from idea to CAD to working object: modelling, material choice, slicing, printing and validation. The winch shows that a well-thought-out architecture (worm-gear reduction) can handle heavy loads even in plastic, and paves the way to a metal version. These builds advanced my skills in design for additive manufacturing (DfAM), tolerance management and the material / function / cost trade-off.
